SpaceX Dragon supply capsule receives astronauts on board

Hawthorne-based SpaceX made more history Saturday morning at the International Space Station when astronauts climbed into the Dragon capsule.

The astronauts are unloading a half-ton of cargo that includes food, clothes, batteries and some student science experiments.

One astronaut said the capsule has that "new car smell."

"The smell inside smells like a brand new car," reported NASA astronaut Donald Pettit. The compartment was brilliantly white and, he noted; clean, no dirt or other particles appeared to be floating around.

SpaceX is the first private company to send a vessel to the space station. It's run by Elon Musk, a billionaire who helped create PayPal and founded the electric car company Tesla Motors.

NASA is turning over orbital delivery work to American businesses so it can focus on getting astronauts to asteroids and mars. The space agency hopes astronaut ferry trips will follow soon; SpaceX contends its Dragons could be carrying space station astronauts up and down within three or four years.
